Disclaimer: I don't own blue exorcist or any of its characters. The only things I own are my ideas.

Author's note: This story ignores what happens in the anime and focuses on what we know happened in the manga. For the sake of the story I'm going to have Shiro already have Kiro as a familiar and because Yukio was born with his demon blood awakened like Rin, he doesn't need glasses, nor is he able to see demons.

Chapter 1

Standing in the middle of the living room, Shiro looked around what would be his new home. The living room was about medium sized and was connected to the kitchen. From what the now former exorcist could tell, the whole apartment was furnished with everything they would need; for both themselves and the babies. The living room walls were covered in a cream colored wallpaper and the floor was a thick maroon carpet. A large TV was sat against the back wall near the corner, a large couch in front with a glass coffee table in between.

Shiro had no idea how Mephisto could have done all this in sure short notice. Unless he had expected Shiro to end up protecting Yuri's children. "I'm going to check out the bedrooms and see how many there are." Shiro nodded at Yuri and watched her walk down the hallway. Walking into the nicely furnished kitchen, the former exorcist took a seat at the small rectangular kitchen table and pulled out the thick wallets the purple haired demon had given him. The first one he opened up had his picture in the front but not his name. Taking the ID out, Shiro read the new name "Shawn Okumura." The wallet truly had everything he would need, even a faked birth certificate.

"So I guess my name is Shawn now." Looking through the other, knowing it had to be Yuri's. The name on her new ID was Yumi Okumura. It then hit him that they had been given the same last name. Pulling all the documents out, Shiro found the one that almost make him grate his teeth. It was a marriage certificate. He was going to be starting his new life as a married man. He then found the twins birth certificates. There official names were Rin and Yukio Okumura. If Shiro really thought about it, being a married couple would make since considering that they were going to be a family. Shiro carefully put the documents and ID's back into the wallets.

"Hey Shiro, come here and look at the bedrooms." Shiro stood from the table, pushing the chair back under. He suddenly got a bad feeling. Walking down the small hallway, Shiro noticed that there were two bedrooms and a bathroom. There was a second bedroom near the kitchen. Yuri was standing in the doorway of the bedroom across from the bathroom. "The baby room is so cute. Rin and Yukio look adorable in their new crib." Shiro noticed that Yuri wasn't holding the babies anymore. Shiro followed his new wife into the baby room and had to admit it did look nice. The walls were painted white with a baby blue pattern. The carpet in the small room was dark blue instead of maroon like the living room. There was a crib that the twins were now in, a table to change diapers, a dresser, and other things that they would need.

"It is nice." Shiro wasn't sure how to bring up the topic of their fake marriage. Yuri seemed to be able to tell that there was something on his mind. "Is there something you want to say Shiro?" Snapped out of his thoughts, Shiro sighed and just came out with it.

"It seems that Mephisto made us a married couple. We are now Shawn and Yumi Okumura." There was a pause before Yuri responded. "That makes sense. We are a family now." Shiro walked over to the crib and looked down. Rin was laying on the right side, and Yukio was laying on the left. The only reason Shiro could tell them apart was that Rin was still wrapped in a blue blanket and Yukio in a yellow one. The two had fallen sleep and were now resting. He couldn't get over how precious they were.

Quietly walking out of the room, Shiro then walked to the room at the end of the hall. This room was bigger than the other with a queen sized bed, two side tables, a dresser with a mirror connected to it, a closet, and a shoe rack. Shiro found himself wanting to sigh. Did Mephisto really expect them to sleep in the same bed? He knew that they were supposed to be married, but that didn't mean that they were in a relationship. This was going be awkward.

It was at that moment Yuri popped up behind him. Shiro almost jumped. "The place is small but I like it." She nodded in agreement. "About the sleeping arrangements, I can sleep on the couch if you want. I don't want things to be awkward." Yuri simply smiled at him. "That's ok; you can sleep on the bed to. We'll just be lying next to each other. But you can sleep on the couch if that's more comfortable for you." "I'll think about it."

Even though it was just the afternoon, Yuri and Shiro's bodies were still adjusted to a different time zone. It would be night time in Japan, and the two were starting to get tired. Shiro walked back to the kitchen and grabbed the wallets he had left on the table, carrying them to the bedroom and placing them in the upper drawer of the dresser. Realizing that he hadn't cheeked his other pockets, Shiro dug through them and found a key with a not on it. As well as another wallet with US money in it.

This key is to store away the sword and gun. Thought you would need it. There's a trunk in the closet you can put them in.

The closet was larger than he had thought with a pair of doors that opened outward. It didn't take long for Shiro to find the trunk that was mentioned. The trunk was long and deep, with a lock in the middle. Inserting the key into the trunk, Shiro opened it to find a small box inside. Most likely for the gun, as well as red sword sleeve with a black strap. Shiro placed the gun within the box and Kurikara in the sleeve. Then closed the trunk, locking it back.

Once that was finished, Shiro walked over to the window and looked out. It was clouded out, snow falling from the sky. The sidewalk down below was covered in thick snow, the street was mostly clear for traffic. It was then that Shiro realized that it was warm inside. There had to be a heater. It was found easily. Shiro walked back into the living room and saw Yuri sitting on the couch watching a random TV channel. Yuri and Shiro both spoke Japanese and English, so they wouldn't have any trouble blinding in.

The curtains were pulled away from the window, allowing light to come in. Shiro walked over to the front door, opened it and looked out. What he saw was a hallway with doors that lead to other apartments. Closing the door, Shiro walked back into their apartment and sat down beside Yuri. The program that was on wasn't very interesting but he watched anyway. He drifted of a few times and before he knew it Yuri was shaking him awake. It was late afternoon and she had cooked them supper. Apparently there was food in the kitchen. The two ate in silence. Yuri had already taken care of the babies while he was asleep.

Shiro helped Yuri clean up and after a few more hours of mindless TV watching, Shiro made sure the door was locked and laid down on the couch. It was just too soon to be sleeping in the same bed as Yuri.

The next morning Shiro woke up to the sound of someone knocking on the door. Sitting up, he stretched his arms over his head and let out a loud yawn. Shiro dragged himself over to the door and looked through the peep out to see if anyone was there. When he didn't see anyone, he unlocked the door and looked down both ends of the hallway. But still didn't see anyone. Shrugging it off, Shiro was about to close the door when he heard a very familiar meow.

Looking down, Shiro saw a cat carrier in front of his door. Leaning down, Shiro looked inside and saw Kuro. The cat demon looked at him with excitement and meowed louder. Shiro picked up the cat carrier and sat in down in the living room. He let Kuro out and watched the cat run around. Mephisto must have sent him his familiar, which he was grateful for. It was then that he heard one of the babies start crying. It turned out to be Yukio, who needed a diaper change. Shiro ended up changing Rin as well not long later.

As time went by, Shiro and Yuri, who was known as Shawn and Yumi Okumura to everyone else, became friends with the neighbors. Shiro was able to quickly get a job at a local church and became a priest. Yuri stayed home to watch the children. Before they knew it, the twins had gotten bigger and were starting to crawl and learn how to speak. Rin loved to crawl after Kuro, who would run from the curious baby. This would lead to Shiro playfully yelling out 'Run Kuro run, he's catching up to you." Rin's fist word ended up being 'cat' while Yukio's was 'mama'. They were soon celebrating the twin's first birthday, giving them both a small smash cake to mess up. Rin had gone down on his, covering himself with cake and frosting. Yukio on the other hand didn't really touch his too much, but he did dig his little fingers in it.

It was a few years after that that they were able to move into a bigger place. Which had three rooms and two bathrooms. Rin and Yukio still shared a room, each with their own toddler bed.

It was five years after leaving Japan, and Shiro and Yuri couldn't deny that they had developed feelings for each other, if not fallen in love. The twins were going to starting school soon, having been held back a year for their late birthday.

Shiro had been sitting in the living room when Yuri told him the news that would stun him for a good few hours. "Shiro, there's something I need to tell you." Shiro had gotten a bad feeling that this wasn't going to be good. "What is it?" He didn't want to ask, but he knew he had to. "Well you see, I'm pregnant with your baby." Great, another kid to keep track of. Shiro had no idea how to respond to that without sounding stupid, so he just nodded. "At least we still have the baby things from when Rin and Yukio were still babies." Shiro finally said.

A few weeks before school started, a young boy about the twins age moved in next door with his mother. The boy would become best friends with Rin.

Mephisto sat in his office at True cross academy. He was waiting for someone and seemed to be getting aggravated with their inability to show up on time. Finally Amaimon appeared in his office, seemingly unaware of his brother's irritated mode. "I'm here big brother, you wanted something?" The purple haired demon wanted to yell at him for being late but stopped. There was no point trying to get that through his younger brother's thick head. Beside's he needed him for something else.

"Yes I do need something. I need you to do something for me." Amaimon seemed interested unaware of what his brother had in mind. "I need you to be a human child and keep an eye on our little brothers while they grow up." The confused look on the earth king's face clearly said that he had no idea he was supposed to do that. Nor was he interested in finding out how.

Amaimon knew by the look on Mephisto's face that he was dead serious. But before he could try to run away, Mephisto had grabbed him by the collar and held him in place. "I'm going to sealing your demon heart away for a while. So get used to being human." Mephisto's hand was then thrust into Amaimon's chest. What was pulled out was a glowing flower with green petals and a red center. The demon heart was then sealed within a glass orb.

Letting go of Amaimon's collar, Mephisto poofed the orb away and watched Amaimon's green hair darken until it was jet black and his yellow eyes became blue. The king of earth then shrank until he was the size of a five year old, which was what Mephisto wanted. Amaimon glared at Mephisto from where he sat on the floor, swallowed in his now to big clothes. "You're going to be the kid in a fake family. This will be your mother for the time being." Mephisto snapped his fingers and a human woman walked inside the office. She had dark brown hair with brown eyes. "Her name will be 'Karen Harsh', and yours will be 'Andy Harsh.'"

Mephisto then poofed new clothes onto Amaimon, who was still glaring murderously at him. "Who's going to be the father in this fake family?" Amaimon asked through clinched teeth. "Me of course. I will be the distant father who pays child support." "I hate you." Mephisto grinned. "Aww, look at that, we already have a strained relationship." A serious look then replaced the playful one on Mephisto's face. "You'll get your demon heart back when I saw so. So get used to it." Mephisto then snapped his fingers and the human woman and former demon king vanished from his office.

"This is going to be interesting."
